Description

Technical Field

[0001] This invention relates to the field of leather processing technology, and in particular to a leather spraying machine. Background Technology

[0002] A leather spraying machine is a piece of equipment used for leather surface treatment. It primarily applies a paste evenly to the leather surface through spraying to improve its appearance, increase water and stain resistance, or enhance abrasion resistance. Spraying machines are commonly used in leather finishing, dyeing, and coating reinforcement processes. The spraying device precisely applies the leather paste to the leather surface to achieve a uniform coating effect.

[0003] When using a spray gun to coat and reinforce the surface of leather, the leather is usually placed flat on a conveyor belt. Then, the first motor is started to drive the rotating shaft, which in turn drives the conveyor belt to transport the leather into the spray gun. At this point, the diaphragm pump is started to draw the protective agent liquid from the storage tank into the second hose through the first hose. Finally, it is sprayed out from the spray nozzle frame to coat the leather for coating and reinforcement. Because the surface of leather is very prone to dust and impurities during the early processing, transportation, and storage, these dust and impurities can prevent the protective agent from evenly covering the leather surface, resulting in uneven coating thickness and rough surface after spraying, which affects the processing quality of the leather. When the dust and impurities fall off later, they will also take away the protective agent, making it unable to provide good protection for the leather and affecting the spraying effect and the final quality of the leather. Summary of the Invention

[0004] This invention addresses the problem that during the early stages of processing, transportation, and storage, dust and impurities easily adhere to the surface of leather. These dust and impurities hinder the even coverage of the protective agent on the leather surface, leading to uneven coating thickness and rough surface after spraying, thus affecting the processing quality of the leather. Furthermore, when the dust and impurities fall off later, they also carry away the protective agent, preventing it from providing adequate protection for the leather and affecting the spraying effect and the final quality of the leather. Therefore, this invention proposes a leather spraying machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a leather spraying machine, comprising a spraying machine body, wherein round shafts are symmetrically installed through the inner wall of the spraying machine body, and a conveyor belt is sleeved on the outer surface of the round shafts; a first motor is provided on one side of the spraying machine body, wherein the output end of the first motor is fixedly installed on one side of one of the round shafts by means of a coupling; a storage box is provided on one side of the spraying machine body, wherein a first flexible hose is installed through one side of the storage box; a diaphragm pump is provided on one side of the spraying machine body, wherein one end of the first flexible hose is fixedly installed at the inlet of the diaphragm pump, and a second flexible hose is fixedly installed at the outlet of the diaphragm pump; a spray pipe frame is provided on the inner wall of the spraying machine body, wherein one end of the second flexible hose passes through one side of the spraying machine body and is connected through one side of the spray pipe frame; a cleaning device is provided on one side of the spraying machine body, wherein the cleaning device can use a fan to create a negative pressure state inside the dust suction hood, and then drive the dust suction hood to move back and forth against the leather surface on the conveyor belt through a drive mechanism, thereby adsorbing and cleaning the dust and impurities attached to the surface.

[0006] The effects achieved by the above components are as follows: When using the spray gun body to coat and reinforce the surface of leather, the leather is usually placed flat on the conveyor belt. Then, the first motor is started to drive the shaft to rotate, which in turn drives the conveyor belt to transport the leather to a certain position. Then, the conveyor stops, and the cleaning device is started to clean the surface of the leather, adsorbing and cleaning away the dust and impurities attached to the surface. This allows the protective agent to be evenly covered on the leather during the subsequent protective agent spraying process, making the spraying more uniform and improving the spraying effect of the protective agent and the final quality of the leather after processing. After cleaning, the conveyor belt can continue to rotate to transport the leather into the interior of the spray gun body. Then, the diaphragm pump is started to draw the protective agent liquid in the storage tank into the second hose through the first hose, and finally sprayed out by the spray gun frame to coat the leather for coating and reinforcement processing.

[0007] Preferably, the cleaning device includes a bracket and a U-shaped frame, wherein a portable mechanism is provided between one side of the bracket and one side of the shotcrete machine body, and one end of the bracket abuts against one side of the shotcrete machine body; a sliding groove is provided on one side of both ends of the bracket; a driving mechanism is provided between the inner wall of the bracket and one side of the U-shaped frame, for driving the U-shaped frame to move up and down and left and right; a dust suction hood, wherein one side of the dust suction hood is fixedly installed on one side of both ends of the U-shaped frame; a fan, wherein one side of the fan is fixedly installed on one side of the bracket; a third hose, wherein both ends of the third hose are respectively installed through the air inlet of the fan and one side of the dust suction hood; a rack frame, wherein both ends of the rack frame are slidably installed in the inner walls of the two sliding grooves, and one side of its inner wall is slidably connected to one end of the dust suction hood; and a plurality of cleaning brushes, wherein both ends of the cleaning brushes are respectively installed through the inner walls of both sides of the dust suction hood, and a gear is fixedly installed on one side of the cleaning brush, wherein the outer surface of the gear meshes with one side of the rack frame.

[0008] The effect achieved by the above components is as follows: By setting up a cleaning device, before using the main body of the spray gun to coat and reinforce the surface of the leather, the bracket is first fixedly installed on one side of the main body of the spray gun via a casual mechanism. Then, after the conveyor belt transports the leather to a certain position and stops moving, the drive mechanism can be activated to drive the U-shaped frame downward, causing the dust hood to move downward as well until one side abuts against the leather, so that the outer surface of the cleaning brush inside also abuts against the surface of the leather. When the dust hood moves downward, it will also drive the rack frame to slide downward in the inner wall of the chute to a certain position. At this time, the blower can be activated to ventilate the inner wall of the dust hood through the third hose. Air is drawn in and discharged through the fan outlet, creating a negative pressure state on the inner wall of the dust hood. This allows the dust and impurities on the leather to be absorbed and cleaned. Simultaneously, the drive mechanism moves the U-shaped frame left and right, causing the dust hood to move back and forth between the inner wall of the rack and the leather. The gears on the cleaning brush mesh and rotate on the rack, rotating and cleaning the surface of the leather, removing firmly attached dust and impurities. These are then absorbed by the dust hood. This ensures that the protective agent is evenly applied to the leather during subsequent protective coating processes, resulting in a more uniform coating, improved coating effect, and higher final quality of the leather after processing.

[0014] The effect achieved by the above components is as follows: by setting up a drive mechanism, the electric telescopic rod can be started to drive the U-shaped frame and the dust hood to move downwards, and then the second motor can be started to drive the reciprocating screw to rotate, thereby driving the slider to move back and forth in the inner wall of the bracket, thereby driving the electric telescopic rod, the U-shaped frame and the dust hood to move back and forth, and cleaning the leather surface.

[0015] Preferably, a reinforcing rod is symmetrically fixedly installed on the outer surface of the output end of the electric telescopic rod, and one side of the reinforcing rod is fixedly installed on one side of the U-shaped frame.

[0016] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the output end of the electric telescopic pole and the U-shaped frame can be increased, making the connection more secure and stable.

[0017] Preferably, the casual clothing mechanism includes a locking block, wherein one side of the locking block is fixedly mounted on one side of the bracket, and both one side of the bracket and one side of the locking block are provided with a first threaded hole; a locking groove is provided on one side of the shotcrete machine body, wherein the locking block is inserted into the inner wall of the locking groove, and a second threaded hole is provided on one side of the inner wall of the locking groove; and a bolt, wherein one end of the bolt is screwed into the inner wall of the first threaded hole and the second threaded hole.

[0018] The effect achieved by the above components is as follows: by setting up a convenient mounting mechanism, before using the shotcrete machine body, the clips on the bracket can be inserted into the slots, and then one end of the bolt can be screwed into the first threaded hole and the second threaded hole, so that the bracket can be fixedly installed on the shotcrete machine body, which is convenient for later cleaning and use. When not in use, it can be disassembled for easy replacement and maintenance.

[0019] Preferably, a connecting rope is fixedly installed at one end of the bolt, and the connecting rope is fixedly installed on one side of the bracket.

[0020] The effect achieved by the above components is that by setting a connecting rope, the bolt can be fixedly installed on one side of the bracket, so that it is not easy to lose after being pulled out from the first threaded hole and the second threaded hole.

[0021] Preferably, a collection device is provided between one side of the support and the outlet of the fan. The collection device includes a collection box frame, wherein the outer surface of the collection box frame is fixedly installed on one side of the support; a fourth flexible hose, wherein both ends of the fourth flexible hose are respectively installed through the outlet of the fan and the outer surface of the collection box frame; two locking blocks, wherein one side of the locking blocks is fixedly installed on one side of the collection box frame; a collection box, wherein the outer surface of the collection box is inserted into the inner wall of the collection box frame; and two locking rods, wherein the outer surface of one end of the locking rod is inserted into the inner wall of the locking block.

Then, it can be rotated to a certain angle, and the locking rod on its outer surface can be inserted into the inner wall of the locking block, thereby fixing the collection box inside the collection box frame. When the blower absorbs and cleans the dust and impurities on the leather through the third hose and the dust hood and discharges them to the blower outlet, they will enter the fourth hose and then enter the collection box inside the collection box frame for collection, which is convenient for later disposal. At the same time, it also prevents dust and impurities from floating in the air and re-attaching to the leather, thus assisting the cleaning device in cleaning.

[0023] Preferably, a rubber block is fixedly installed on the outer surface of the clamping rod, wherein the rubber block is inserted into the inner wall of the clamping hole block along with the clamping rod.

[0024] The effect achieved by the above components is that by setting the rubber block, the contact friction of the outer surface of the lever can be increased, making it more securely fixed and less likely to slip out when it is locked into the inner wall of the locking hole block.

[0025] In summary, the beneficial effects of the present invention are as follows: By setting up a cleaning device, before using the spray gun body to coat and reinforce the leather surface, the bracket is first fixed to one side of the spray gun body via a portable mechanism. Then, after the conveyor belt transports the leather to a certain position and stops moving, the drive mechanism can be activated to move the U-shaped frame downwards, causing the dust hood to move downwards as well until one side abuts against the leather, so that the outer surface of the cleaning brush inside also abuts against the leather surface. As the dust hood moves downwards, it will also cause the rack frame to slide downwards in the inner wall of the chute to a certain position. At this time, the blower can be activated to draw air from the inner wall of the dust hood into the blower through the third hose. The dust is discharged through the outlet, creating a negative pressure state on the inner wall of the vacuum hood. This allows the dust and impurities on the leather to be absorbed and cleaned. Simultaneously, the drive mechanism moves the U-shaped frame left and right, causing the vacuum hood to move back and forth between the inner wall of the rack and the leather. The gears on the cleaning brush mesh and rotate on the rack, rotating and cleaning the surface of the leather, removing firmly attached dust and impurities. These are then absorbed by the vacuum hood. This ensures that the protective agent is evenly applied to the leather during subsequent protective coating processes, resulting in a more uniform coating, improved coating effect, and higher final quality of the leather after processing.

[0028] Reference Figure 1-10As shown, this embodiment discloses a leather spraying machine, including a spraying machine body 1. Round shafts 4 are symmetrically installed through the inner wall of the spraying machine body 1. A conveyor belt 5 is fitted onto the outer surface of the round shafts 4. A first motor 6 is provided on one side of the spraying machine body 1, wherein the output end of the first motor 6 is fixedly installed on one side of one of the round shafts 4 via a coupling. A storage tank 7 is provided on one side of the spraying machine body 1, and a first flexible hose 8 is installed through one side of the storage tank 7. A diaphragm pump 9 is provided on one side of the spraying machine body 1, wherein one end of the first flexible hose 8 is fixedly installed on the diaphragm pump. A second hose 10 is fixedly installed at the inlet and outlet of the membrane pump 9. A spray pipe frame 11 is provided on the inner wall of the shotcrete machine body 1. One end of the second hose 10 passes through one side of the shotcrete machine body 1 and is connected to one side of the spray pipe frame 11. A cleaning device 2 is provided on one side of the shotcrete machine body 1. The cleaning device 2 can use a fan 24 to make the inside of the dust suction hood 27 negative pressure, and then drive the drive mechanism 22 to drive the dust suction hood 27 to move back and forth against the leather surface on the conveyor belt 5 to absorb and clean the dust and impurities attached to its surface. When using the spray gun body 1 to coat and reinforce the surface of leather, the leather is usually placed flat on the conveyor belt 5. Then, the first motor 6 is started to drive the round shaft 4 to rotate, which in turn drives the conveyor belt 5 to transport the leather to a certain position. Then, the conveyor belt stops, and the cleaning device 2 is started to clean the surface of the leather, removing the dust and impurities attached to the surface. This allows the protective agent to be evenly applied to the leather during the subsequent protective agent spraying process, resulting in a more uniform spraying effect and improved final quality of the leather after processing. After cleaning, the conveyor belt 5 can continue to rotate to transport the leather into the interior of the spray gun body 1. At this point, the diaphragm pump 9 is started to draw the protective agent liquid from the storage tank 7 into the second hose 10 through the first hose 8, and finally sprayed out by the spray nozzle frame 11 to coat the leather for coating and reinforcement.

[0029] Reference Figure 1-10As shown, this embodiment discloses a cleaning device 2 including a bracket 21 and a U-shaped frame 26. A portable mechanism 23 is provided between one side of the bracket 21 and one side of the shotcrete machine body 1, with one end abutting against one side of the shotcrete machine body 1. Sliding grooves 29 are provided on one side of both ends of the bracket 21. A drive mechanism 22 is provided, located between the inner wall of the bracket 21 and one side of the U-shaped frame 26, for driving the U-shaped frame 26 to move up and down and left and right. A dust suction hood 27 is fixedly installed on one side of both ends of the U-shaped frame 26. A fan 24 is also provided. One side is fixedly installed on one side of the bracket 21; the third hose 25, wherein the two ends of the third hose 25 are respectively installed through the air inlet of the fan 24 and one side of the dust hood 27; the rack frame 28, wherein the two ends of the rack frame 28 are respectively slidably installed in the inner wall of the two slide grooves 29, and one side of its inner wall is slidably connected to one end of the dust hood 27; a plurality of cleaning brushes 210, wherein the two ends of the cleaning brushes 210 are respectively installed through the inner wall of the dust hood 27 on both sides, and a gear 211 is fixedly installed on one side of the cleaning brushes 210, wherein the outer surface of the gear 211 meshes with one side of the rack frame 28. Before applying a coating to the leather surface using the spray gun body 1, the cleaning device 2 is installed. Before the spray gun body 1 is used to reinforce the leather surface, the bracket 21 is fixedly installed on one side of the spray gun body 1 by the clothing mechanism 23. After the conveyor belt 5 transports the leather to a certain position and stops moving, the drive mechanism 22 can be activated to drive the U-shaped frame 26 downward, which in turn drives the dust hood 27 downward until one side abuts against the leather, so that the outer surface of the cleaning brush 210 inside also abuts against the surface of the leather. When the dust hood 27 moves downward, it will drive the rack frame 28 to slide downward in the inner wall of the slide chute 29 to a certain position. At this time, the blower 24 can be activated to draw air from the inner wall of the dust hood 27 through the third hose 25. The dust and impurities are discharged from the outlet of the blower 24, creating a negative pressure state on the inner wall of the dust suction hood 27. This allows the dust and impurities on the leather to be absorbed and cleaned. At the same time, the drive mechanism 22 drives the U-shaped frame 26 to move left and right, which in turn causes the dust suction hood 27 to move back and forth on the inner wall of the rack frame 28 and on the leather. The gear 211 on the cleaning brush 210 meshes and rotates on the rack frame 28, rotating and cleaning the surface of the leather to remove the firmly attached dust and impurities. These are then absorbed by the dust suction hood 27. This allows the protective agent to be evenly applied to the leather during the subsequent protective agent spraying process, resulting in a more uniform spraying effect and improved final quality of the leather after processing.

[0030] Reference Figure 1-10As shown, this embodiment discloses that bearings 212 are fixedly installed on the outer surfaces of both ends of the cleaning brush 210, and the outer ring of the bearing 212 is fixedly installed in the inner wall of the dust collection cover 27. By setting the bearings 212, the cleaning brush 210 can be easily rotated, while also reducing rotational wear between the cleaning brush 210 and the dust collection cover 27, thus improving its service life. Several ball bearings are rotatably installed on one side of the dust collection cover 27, and the ball bearings are located on the side of the dust collection cover 27 away from the U-shaped frame 26. By setting the ball bearings, the contact friction between the dust collection cover 27 and the leather can be reduced, facilitating cleaning by moving back and forth.

[0031] Reference Figure 1-10 As shown, this embodiment discloses a drive mechanism 22 including a reciprocating lead screw 221, one end of which is installed through and mounted on one side of the inner wall of the bracket 21; a second motor 222, the output end of which is fixedly mounted on one side of the reciprocating lead screw 221 by means of a coupling; a slider 223, which is slidably mounted in the inner wall of the bracket 21, and the inner wall is slidably connected to the outer surface of the reciprocating lead screw 221; and an electric telescopic rod 224, one side of which is fixedly mounted on one side of the slider 223, and the other output end is fixedly mounted on one side of the U-shaped frame 26. By setting up the drive mechanism 22, the electric telescopic rod 224 can be activated to drive the U-shaped frame 26 and the dust hood 27 to move downwards. Then, the second motor 222 is activated to drive the reciprocating screw 221 to rotate, thereby causing the slider 223 to move back and forth within the inner wall of the bracket 21. This, in turn, causes the electric telescopic rod 224, the U-shaped frame 26, and the dust hood 27 to move back and forth, cleaning the leather surface. Reinforcing rods 225 are symmetrically fixedly installed on the outer surface of the output end of the electric telescopic rod 224, with one side of the reinforcing rod 225 fixedly installed on one side of the U-shaped frame 26. By setting up the reinforcing rods 225, the connection area between the output end of the electric telescopic rod 224 and the U-shaped frame 26 can be increased, making the connection more secure and stable.

[0032] Reference Figure 1-10As shown, this embodiment discloses a portable mechanism 23 including a locking block 231, one side of which is fixedly mounted on one side of a bracket 21. Both one side of the bracket 21 and one side of the locking block 231 have a first threaded hole 232. A slot 234 is provided on one side of the shotcrete machine body 1, with the locking block 231 inserted into the inner wall of the slot 234. A second threaded hole 235 is provided on one side of the inner wall of the slot 234. A bolt 233 is provided, with one end of the bolt 233 screwed into the inner walls of the first threaded hole 232 and the second threaded hole 235. By providing the portable mechanism 23, before using the shotcrete machine body 1, the locking block 231 on the bracket 21 can be inserted into the slot 234, and then one end of the bolt 233 can be screwed into the first threaded hole 232 and the second threaded hole 235, thereby fixing the bracket 21 onto the shotcrete machine body 1. This facilitates later cleaning and use, and when not in use, it can be disassembled for easy replacement and maintenance. A connecting rope 236 is fixedly installed at one end of the bolt 233, and the other end of the connecting rope 236 is fixedly installed on one side of the bracket 21. By setting the connecting rope 236, the bolt 233 can be fixedly installed on one side of the bracket 21, so that it is not easy to lose it after being pulled out from the first threaded hole 232 and the second threaded hole 235.

[0033] Reference Figure 1-10 As shown, this embodiment discloses a collection device 3 disposed between one side of the support 21 and the outlet of the fan 24. The collection device 3 includes a collection box frame 32, wherein the outer surface of the collection box frame 32 is fixedly installed on one side of the support 21; a fourth hose 31, wherein both ends of the fourth hose 31 are respectively installed through the outlet of the fan 24 and the outer surface of the collection box frame 32; two locking blocks 33, wherein one side of the locking block 33 is fixedly installed on one side of the collection box frame 32; a collection box 34, wherein the outer surface of the collection box 34 is inserted into the inner wall of the collection box frame 32; and two locking rods 35, wherein the outer surface of one end of the locking rod 35 is inserted into the inner wall of the locking block 33. By setting up the collection device 3, after the bracket 21 is installed, the collection box 34 can be manually inserted into the inner wall of the collection box frame 32. Then, it can be rotated to a certain angle and the locking rod 35 on its outer surface can be inserted into the inner wall of the locking hole block 33. Thus, the collection box 34 can be fixedly installed inside the collection box frame 32. When the blower 24 absorbs and cleans the dust and impurities on the leather through the third hose 25 and the dust suction hood 27 and discharges them to the outlet of the blower 24, they will enter the fourth hose 31 and then enter the collection box 34 inside the collection box frame 32 for collection. This facilitates later emptying and also prevents dust and impurities from floating in the air and re-attaching to the leather, thus assisting the cleaning device 2 in cleaning.

[0034] Reference Figure 1-10As shown, this embodiment discloses that a rubber block 36 is fixedly installed on the outer surface of the locking rod 35, wherein the rubber block 36 is inserted into the inner wall of the locking hole block 33 along with the locking rod 35. By setting the rubber block 36, the contact friction of the outer surface of the locking rod 35 can be increased, so that when it is locked into the inner wall of the locking hole block 33, the limiting fixation is more secure and it is not easy to slip out.

[0035] The working principle is as follows: Before applying a coating reinforcement treatment to the surface of the leather using the main body 1 of the spraying machine, the locking block 231 on the bracket 21 can be inserted into the locking slot 234. Then, one end of the bolt 233 is screwed into the first threaded hole 232 and the second threaded hole 235, thereby fixing the bracket 21 onto the main body 1 of the spraying machine. Then, the collection box 34 is manually inserted into the inner wall of the collection box frame 32. Then, it is rotated to a certain angle, and the locking rod 35 on its outer surface is inserted into the inner wall of the locking hole block 33, thereby fixing the collection box 34 inside the collection box frame 32. When using the spray gun body 1 to coat and reinforce the surface of leather, the leather is usually placed flat on the conveyor belt 5. Then, the first motor 6 is started to drive the round shaft 4 to rotate, which in turn drives the conveyor belt 5 to rotate and transport the leather to a certain position. When the movement stops, the electric telescopic rod 224 is started to drive the U-shaped frame 26 to move downward, which in turn drives the dust hood 27 to move downward until one side abuts against the leather, so that the outer surface of the cleaning brush 210 inside also abuts against the surface of the leather. When the dust hood 27 moves downward, it will also drive the rack frame 28 to slide downward in the inner wall of the slide chute 29 to a certain position. At this point, the blower 24 can be started, drawing air from the inner wall of the dust hood 27 through the third hose 25 and expelling it from the outlet of the blower 24. This creates a negative pressure state on the inner wall of the dust hood 27, adsorbing and cleaning dust and impurities from the leather. Simultaneously, the second motor 222 is started, driving the reciprocating screw 221 to rotate. This causes the slider 223 to move back and forth within the inner wall of the bracket 21, which in turn causes the dust hood 27 to move back and forth on the inner wall of the rack and pinion 28 and on the leather. The gear 211 on the cleaning brush 210 meshes and rotates on the rack and pinion 28, rotating and cleaning the surface of the leather. The firmly attached dust and impurities are cleaned up and then sucked into the outlet of the blower 24 through the dust suction hood 27, entering the fourth hose 31 and then into the collection box 34 inside the collection box frame 32 for easy disposal later. This also prevents dust and impurities from floating in the air and re-adhering to the leather. The auxiliary cleaning device 2 performs cleaning, so that when the protective agent is sprayed later, it can evenly cover the leather, making the spraying more uniform and improving the spraying effect and the final quality of the leather after processing.
